The results showed that there is no much reduction of the fatigue life in corrosive environment, which is 90% of the air fatigue strength.
The mechanical properties at room temperature are ultimate tensile strength of 953 MPa, yield strength of 569 MPa , elongation of 27.8% and section area reduction of 74 %.
Test results and discussion 3.1 Stress-fatigue life data (S-N curve) Fig. 3 presents the S-N results for air and corrosion less than 1×108 cycles.
It is because that the former alloys have less ductility with elongation below 18% and the section area reduction of 55 %, compared to the duplex stainless steel 2507 with high elongation of 27.8% and section area reduction of 74 %.
In contrast, there is no much reduction in the fatigue limit in corrosive environment due to high content of Cr.

A reduction in the amount of albite and quartz associated with mullite formation was observed when increasing the amount of lithium oxide or the temperature.
Although usually opaque, some stoneware is so thinly potted that it is somewhat translucent. [1][2] The typically firing temperatures of stoneware will be between 1180°C to 1280°C.[3] For more carefully selected, prepared and blended raw materials, fine stoneware, is used to produce tableware and art ware.[4] At present, the tendency of increasing energy demand, rising energy prices, and reinforcement of global warming countermeasures, a reduction in the energy consumption in the ceramic manufacture has drawn attention.
Crystalline phases were identified by comparing the intensities and positions of the Bragg peaks to those listed in the Joint Committee on Powder Diffraction Standards data files.
The reduction in the amount of albite and quartz associated with mullite formation at higher firing temperature was observed in most of the samples.
The results showed that a reduction in the amount of albite and quartz associated with mullite formation was observed when increasing the amount of Li2O or the temperature.

This paper summarizes the relevant research data at home and abroad in recent years, briefly introduces the functions of different kinds of nano materials, summarizes the application of nano adsorption technology in sewage treatment, and explores the adsorption mechanism of various nano materials on various pollutants in water, At the same time, the research progress of several common nano adsorption materials in removing water pollutants is summarized, and the risks existing in the application of nano materials are pointed out.
Graphene oxide is the product of graphene surface oxidation, which can be transformed into graphene after reduction.
The removal mechanism of heavy metal ions by nano zero valent iron includes reduction and adsorption.
When the standard electrode potential of heavy metal ions is lower than that of iron, adsorption mainly occurs; When the standard electrode potential of heavy metal ions is slightly greater than that of iron, adsorption and reduction work at the same time; When the standard electrode potential of heavy metal ions is much greater than that of iron, reduction mainly occurs.
Therefore, the surface area of zero valent iron is an important parameter to control the reduction rate.

A reduction of Ni concentration from 80 to 50 percent was observed as the Sm concentration increased from 0 to 25%.
Introduction Thin films of rare earth-transition metal (RE-TM) amorphous magnetic alloys are most notable as data storage media because their recording bits are free from grain boundary effects thereby, allowing ultra high areal density memory capacity.
In both read and write elements of magnetic recording heads and MRAM devices, fast switching time is becoming relevant for achieving higher data transfer rates.

According to the data, it is clear that the total L/B acidity and the medium and strong L/B acidity of the catalysts increase notably after the combined-modification measurement.
It can be seen that the modified nanoscale HZSM-5 catalyst is highly effective for saturated sulfur compounds reduction, and its reduction reaches almost 100%.
Thiophene is generally considered difficult to remove from gasoline with a reduction about 87%, whereas for alkyl-thiophenes, the reactivity is higher and the reduction is 92%.
Sulfur compound reduction over the modified catalyst.
Since the major sulfur compounds in FCC gasoline are thiophene species, the reduction of thiophenic compounds is critical for sulfur reduction of gasoline.

The data acquisition system consisted of AD card, personal computer and homemade acquisition
program in Pascal.
At the same graph average stiffness reduction En(N)/En(0) is also presented.
The optical signal continued to increase until the stiffness reduction in the first part of the rod fell to 0.76.
When stiffness reduction started its final decay, the optical signal started to decrease, too.
The evaluated average stiffness reductions for both rods showed a three-phase decay: initial decrease, linear reduction, and final decrease before failure.

The ratio, F /σ , between the load of the SP-C test
(F) and the stress of the uniaxial test (σ) was determined to be 2.4 for the same value of the
Larson-Miller parameter in the creep rupture data.
Details of the conventional SP test and the data analysis are given in References [1-8].
The SP-C rupture data is plotted against Larson-Miller parameter (LMP) in Fig. 6, which has been generally used for arranging the creep rupture test results under various test conditions.
In this study, the correlation between the load of the SP-C test and the stress of the uniaxial test was examined to establish quantitatively correlation between both test data.
This figure was made so that the SP-C rupture data of the aged steel were completely coincident with the uniaxial data.

Data were measured based upon the 24 solar terms of the traditional Chinese lunisolar calendar and the results of Great Heat in comparison with other solar terms showed significant differences.
Reduction of exhaust heat contributes to the lowering of maximum daytime temperatures.
Weather station measurements and meteorological data above the pavement (the measurement items includes wind speed, air temperature, relative humidity and irradiation) are shown in Table 1.
Data were taken from May 2011 to August at 10 minute intervals.
Meteorological data measurements during the Great Heat terms show no rainfall before or after the Great Heat.
